The performance should be just that of the underlying MPI library and  
the hardware. The C++ bindings should have negligible overhead.

The main performance-related design issue was about user-defined data  
types, for which an MPI_Datatype can be constructed using the  
Boost.Serialization library. The array serialization optimizations  
that have recently been added to the CVS HEAD of the  
Boost.Serialization library ensure that also this part can be done  
without performance penalties. This is also the reason why the latest  
Boost from the CVS HEAD is needed to compile and run the MPI library.
